Industrial Borescope Light Source Comparison
| Comparison | Front-end LED | Rear-end LED + Optical Fiber |
| Installation Method | Several LEDs are installed at the front end | LED light source is installed at the rear (main unit/handle), light guided to front via fiber |
| LED Size & Power | Small-sized LEDs, limited space and power | Single high-power LED, not limited by size at front end, higher power output |
| Light Transmission | Scattered | Focused, directed forward |
| Light Source Position | At the front end; may be blocked by objects or reflect, causing image interference | At the rear; nearly unaffected by front-end interference |
| Impact on Front-end | Generates heat at the front, may cause image blur or affect function | No heat at the front, does not affect image |
| Maintenance Cost | If LED fails, front-end module needs replacement (LED is integrated) | Only need to replace rear LED; if fiber fails, just replace fiber |
| Advantages | 1. Newer tech, lower cost 2. Shorter production cycle | 1. Suitable for long-distance/large space applications2. Better image clarity3. Easier maintenance if LED fails |
| Disadvantages | 1. Low brightness due to small LEDs2. Heat issue limits performance3. Module must be replaced if LED fails | 1. Higher cost (due to fiber)2. Bulky components, longer light path required3. Higher overall design complexity |
